Help reqd - Data declaration

Hi,
I have a problem here. I am analyzing an existing program. This is an active prg in Production.
In that I see usage of an internal table called 'itab1'. On double clicking on it (to find it's data declaration) it takes no-where. It asks if I would like to create it.
In an include program (which in embedded in this main program), I find some declaration as follows:
data: itab&1 like &2 occurs 0 with header line.
Can you help me understand this? I need to change the data declaration for this 'itab1' for an upgrade.
Regards,
Sanju.

Macros are defined using the following statement:
DEFINE conversion.
if &1 is not initial.
&2 = c_X.
else.
&2 = space.
endif.
END-OF-DEFINITION.
You apply it like described bellow:
conversion var_1 var_return.
My guess is that this internal table is being declared using the macro parameter. so, if &1 is valued with "10", that internal table will be named itab10.
Not quite sure about that, but maybe that's what is happening. Try to find the place where the macro is being called and see if &1 value is '1'.

Search help for date field in Editable ALV

Hello Friends,
I am using editable alv using 'reuse_* '.
I have used date as input field. While creating fieldcatlog also i have declared dat as a mkpf-budat.
But i am not getting serach help for date in output.
Is it possible with reuse or i have to go by object oriented ?

Data declaration error in adobe form

hi,
i m just remake a smartform into adobeform.but while doing so it's giving me error regarding data declaration.
I had declare some of internal table as type of defiened type but at code initialzation it giving it's not a internal table.
global data
it_abc type ty_abc,
types :
types: begin of ty_abc,
           ab(8) type c,
           bc(4) type c,
          end of abc.
when i m creating a internal table in code initialization it's giving me that already declared.
code initialization.
data : it_abc type table of ty_abc.
Plz help me out.
Regards
Ricky

Hi Maheshwari,
After the declaration of the TYPES Structure, you need to declare the Internal Table. As follows
TYPES
types: begin of ty_abc,
          ab(8) type c,
          bc(4) type c,
          end of abc,
          tt_abc type standard table of ty_abc initial size 0.
And in Global Declaration you use the newly created Internal Table (which is created using the Types Statement). And in Code Initialization you can use the Global Declaration internal table.

Urgent Help Reqd: Delta Problem....!!!

Hi Experts,
Urgent help reqd regarding follwoing scenario:
I am getting delta to ODS 1 (infosource : 2LIS_12_VCHDR) from R/3. Now this ODS1 gives delta to Cube1. I got one error record which fails when going to cube (due to master data check).And this record would be edited later.
So I thought of re loading cube and using error handling to split request in PSA and load valid records in cube.Later when I have coorect info abt error, I would load erroneous record manually using PSA.
I did following steps:
1)Failed request is not in cube...(setting is PSA and then into target)....also it has been deleted from PSA.
2)Remove data status from source ODS1.
3)Change error handling in infopackage to valid " Valid records update, reporting possible".
4)start loading of cube.
But when I did this I got following message :
 "Last delta update is not yet completed.Therefore, no new delta update is possible.You can start the request again if the last delta request is red or green in the monitor"
But both my requests in cube and ODS are Green...no request is in yellow...!!
Now the problem is :
1) I have lost ODS data mart status
2)how to load valid records to cube, since errorneous record can be edited only after 3- 4 days.
3)How not to affect delta load of tomorrow.
Please guide and help me in this.
Thanks in advance and rest assured I will award points to say thanks to SDNers..
Regards,
Sorabh

Hi Joseph,
Thanks for replying....
I apolgize and I have modified the message above..
I just checked in cube...there is no failed request for today...and neither in PSA....Person who has handed this to me may have deleted this is PSA..and why req is not in failed state in cube...I am not sure..though setting is "PSA and then into data package".....
So how to go frm here....
Thanks

Dynamic data declaration refering to local data defined in another program

Here is the situation:
The standard program SAPICP__ , SAPICF__ and several other of same series have a form routine REPOSITORY_DEVCLASS_ADD. this subroutine in all SAPI* programs has parameter REPOSITORY of type REPOSITORY (declared as internal table with header lines) and type REPOSITORY is declared with different component in each program.
Now the problem is that i need to call subroutine REPOSITORY_DEVCLASS_ADD dynamically from my program and so i want to dynamically declare the table REPOSITORY in my program to pass to this subroutine and as program is not yet loaded into memory i have no way to achieve this.
Can some one help in achieve this?

Hello Fred,
That's a big task, even if it looks "easy". My first idea is, your request can not be covered by dynamic programming. a) every node has a different structure (I guess), b) the code itself has to be adjusted to the nodes in use as well. I.e. when a dynamic data declaration would be possible, the coding has to adhere the used number of nodes.
My recommendation:
- declare as many standard tables (nodes) as possible
- the code for each node has to be implemented
- define the number of used nodes by a parameter or an interface
Have success,
Heinz

Dynamic data declaration

I posted same thread into "Dictionary section"
Hi,
I have a following issue - I am not sure whether this is possible - so I need your feedback/expertise.
I have a custom table (example ZABC) with several fields in it - one of them being TABNAME . Content of that table ZABC is
MANDT TABNAME FIELDNAME ZCHECK
800 KNA1 KUNNR
800 KNA1 NAME1 X
800 KNA1 NAME2 X
800 KNA1 KUNNR
800 KNVV BZIRK X
800 KNAS KUNNR
800 KNAS STCEG
etc.
There is no rule how many entries will be in this ZABC table - I guess it will be less than 20 - but this is not business rule. Also do not know how many different "tables" could be specified.
Fields MANDT and ZCHECK fields are not important at this stage.
The challenge I have is to fetch data for only those fields from their specified physical tables (KNA1, KNVV, KNAS) in internal tables.
In this case I would need to have 3 internal tables one for KNA1, one for KNAS and one for KNVV.
I need to keep those "internal" table with content throughout the entire program for certain validation.
I know that I should dynamically define those internal tables but I have issues not knowing how many tables will be defined in ZABC table and I personally do not want to declare "<fs_itab> TYPE ANY TABLE" 20 or so times as fs_itab1 - fs_itab20.
Is there any way I can dynamically create as many internal tables as needed and keep their content throughout program run-time.
Regards
Goran

All those examples you'all posted are great BUT it does not answer my question nor help me to solve my issue. Maybe I was not clear enough ... or something is wrong with me
Once again.
I have no problem to get a dynamically defined table and fill its content from ONE physicall table. That is pretty straight forward. The issue I have is that I do not know how many dynamically tables I will have to define and later asign to field symbol. Look at my custom table above and you will understand what I am trying to say.
What makes this issue more complex is that, once data fetch from those physicall SAP tables, I have to keep the content for all those internal tables during the entire program run . Second the most, I do not want to limit the program by defining FS "n" times in data declaration section. That is really important since I have no idea how many tables will be accessed.
If I follow the logic from your examples, I will end up overwritting the FS content every time I assign new internal table to FS.
In order to solve this issue, I was thinking that whenever I get the data from SAP table into internal table (field symbol) i export the content of internal table / FS to memory and then retrieve them when needed. This sounds like waky /fuzzy process and I am not aware of anything better. I am old fashion ABAP guy who got certified 1995 and have not seen ABAP for at least 5 years.
I would like that someone either tells me whether I am OK going forard with my "memory" solution or ... in few words gives me hint how to handle multiple dynamicall defined tables AT THE SAME TIME with its content using some OO code.
Thanks
G
P.S.
I have erroneusly opened the same thread twice. Sorry

Data declaration for result of dynamic query

Good day,
can you help me with declaration of data for query result that can be from any columns of any tables.
For example (this is from SAP documentation):
DATA: wa TYPE spfli,
 ftab TYPE TABLE OF STRING.
APPEND 'CITYFROM' TO ftab.
APPEND 'CITYTO' TO ftab.
SELECT DISTINCT (ftab)
 FROM spfli
 INTO CORRESPONDING FIELDS OF wa
 WHERE
 carrid = 'LH'.
WRITE: / wa-cityfrom, wa-cityto.
ENDSELECT.
This is clear to me, but I don't know how to do in case FROM clause is generated dynamically too.
SELECT DISTINCT (ftab)
 FROM (tab1)
Thanks

Doubts in Data Declarations

Hi Xperts

Hi,
Reference Types
You can define reference types locally in your programs or globally in the ABAP Dictionary. You use the following syntax:
TYPES <t> TYPE REF TO ...
After TYPE, there is no reference to an existing data type. Instead, the type constructor occurs:
The type constructor
REF TO DATA
declares a reference <t> to a data object. Fields with type <t> can contain references (pointers) to data objects, that is, instances of data types
The type constructor
REF TO <class>|<interface>
defines a reference type <t> to the class <class> or interface <interface>. Fields with type <t> can contain references (pointers) to instances of the class <class> or of classes that implement the interface <interface>

Is there a Java utility class to help with data management in a desktop UI?

Is there a Java utility class to help with data management in a desktop UI?
I am writing a UI to configure a network device that will be connected to the serial port of the computer while it is being configured. There is no web server or database for my application. The UI has a large number of fields (50+) spread across 16 tabs. I will write the UI in Java FX. It should run inside the browser when launched, and issue commands to the network device through the serial port. A UI has several input fields spread across tabs and one single Submit button. If a field is edited, and the submit button clicked, it issues a command and sends the new datum to the device, retrieves current value and any errors. so if input field has bad data, it is indicated for example, the field has a red border.
Is there a standard design pattern or Java utility class to accomplish the frequently encountered, 'generic' parts of this scenario? lazy loading, submitting only what fields changed, displaying what fields have errors etc. (I dont want to reinvent the wheel if it is already there). Otherwise I can write such a class and share it back here if it is useful.
someone recommended JGoodies Bindings for Swing - will this work well and in FX?

Many thanks for the reply.
In the servlet create an Arraylist and in th efor
